Yes, solar lights are designed to work in the dark. Here's how:

* Solar panels: During the day, the solar panels absorb sunlight and convert it into electricity, which is stored in a battery.

* Dusk sensor: When the sun sets and it gets dark enough, a dusk sensor triggers the light to turn on.

* LED lights: The battery powers the LED lights, which emit a bright glow.

So, solar lights function by utilizing the energy collected during the day to illuminate at night.
